Environmental Metabolomics Applications in Field and Laboratory Studies: From the Exposome to the Metabolome presents an overview of the current state of aquatic environments and problems caused by human pressure and daily life. The presence of contaminants in nature and their effects are evaluated, along with recommendations for preservation. This book not only shows readers how to implement techniques, it also guides them through the process. As metabolomics becomes a more routine technique for environmental studies and future perspectives, a guide for validation and globalization of current approaches is needed.
